The Hard Truth About Storing Fuel
https://www.theorganicprepper.com/storing-fuel/
... Based on my own experiences with modern gasoline not produced in my country (which once produced 1/3 of the fuel tank of every car up there in the US), let´s elaborate on why storing “for the future” may not be an option anymore. ...
Excellent article with many factoids about the chemistry and behaviour of gasoline.
I have a fair bit of gas stored with stabilizer for lawnmower, snowblower, and generator--just in case. Not a huge amount, but enough to run the gene a few hours a day for a week or so. Just basic natural disaster stuff, not TEOTWAWKI.
No problems--yet--but I'm going to rotate it quicker by running some of it through my car.
Unless you have a gigantic tank they won’t deliver. Rotating 5 gallon cans is a PIA. Better than nothing though.
